if you have windows 7 then you click the start button on the bottomand on the right of the menu click control panel and then a bunch of categories with sub links below them. if those catergories dont pop up then click "view by" in the top left and select catergories. you then want to click programs category and underneath programs and features click uninstall a program. it should be the first one.then all you do is scroll and find your game click on it, then up at the top click "unistall/change" or "uninstall" and there you go it will uninstall the program. I hope this helps.

Start Menu > Control Panel > Uninstal Programm... then choose your ones...
